Earnings Per Share [Abstract] |
Net loss per share | 7. Net loss per share Basic and diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding. Potentially dilutive securities were excluded from the diluted calculation because their effect would be anti-dilutive. The following tables set forth the computation of basic and diluted net loss per share: ​
